You are building 240 sqm² living space plus a basement?
Yes, we are building 240 sqm plus basement. Because we have 3 children and are currently expecting twins.
They can be quite expensive. We budget about 1000 to 1200€ each for our two built-in fixtures. Material only, mind you. There is no bathtub, no shower (preparation for barrier-free shower) or shower enclosure etc. included.
Much has already been clarified about the rest. We had around 8000€ for electricity, telephone, and water/sewage.
In the meantime, we have another offer for gas, heating and sanitary and are at 57k with underfloor heating, gas condensing boiler + solar.
What kind of exterior façade will it be? Is there already an offer? 18,000 euros in my opinion is too little for the size of the house.
Yes, that was far too little. The offer is at 25,800€, which I think is okay. It is a normal plastered and painted exterior façade, so no brick.
